To dit'. ywhom it may concern.'

Be it known that l, Jossrn Lnwrnwsrrn, n subject ol thejlling ol Greet Britain, residg et Thorn Cottage, hiddingly, Sussex, England, ne-ve invented certain new and use iul improvements in the Construction of Turbines, of which the following is c speciicotion.

The object of this invention is the constructing oi' e. turbine, so that hy e simple movement of e. lever, the direction ci roto-- tion can he reversed, thus enabling the turbine to run in two .lirections.

lily invention. will he clearly understood from tlio/iioilowing description sided hy the accompanying dren/ings in which Figure l. is n side 'view of s turbine with eert oi the. casing broken sway to show the interior constreetion which is in section. Fig. 2. is e similar view to Fig. i hut showing e modified forni of the interior construction. According to this invention, l construct c turbine or rotny engine from two disks 1, 2, mounted loosely on on axle, 3, and having projecting rings 1i, 5, from their inside feces, which rings et, 5, are provided with pockets or recesses 6 vor the like on both feces.

y The projecting rings fi, 5, ot' each disk 1, 2, are in engagement with each other es shown, and the pocksiii ,or recesses re of such s. construction. theft/lie stoom can poss along the meeting surfaces ol the rings 5, ironi one to snother, the recesses o nearest the eide 8 being Prefcriblv siiialicr then those farthest from t-.ie ortie so cs to :tllow of the full work c l' I i or the steam, not suon arrange-.nient may he reversed, or the recesses he oi the seme size tnrohghout.

The disks 4, 5, nre situiite in e cesing 7, fio sind the Q .Xle 3 also es. s. clutch f5, which engages either oi the t. 2, land such clutch S is in connection oy t rod 9 passed through :i hollow portion ol' the side 3, and connected to e rocking hoorn 10 pivoted on i5 the operating lever 11, the other end of the rocking herrin 1() heing connected to the rod 12 carrying the brakes 13, which ect on the disks 1, 2. The steam edinittcd neer the' axle 3, sind exhausted from the casing My invention in sini le form is shown in Fig. 1, Wherein'eoch dis i, 2, carries n single series of concentricslly arranged rings, nest f ing with each other when in place, hut in `5 Fig. 2, l show two disks and a. double web each carrying o set or series of concentricslly arranged rings Destino' with each other, which construction will eiectuolly prevent any end thrust duo to the action of the steam.

The disk l es in Figs. 1 end 2, is provided with o. collar or portion 1'?, which encircles the axle 3, und is also shaped nt 18 to receive the end of the clutch 8 so as to become engaged therewith, sind revolve with the axle 3, hut in the construction shown in Fig. 2, the collar is extended at 19 end provided at its end with n disk 1a which csrries the rings 4l looking towards the rings el. In this construction, the disk 2 (also rovided es is the cose with the disk l, witi ineens for the clutch 8 to engage into to revolve saine with the axle) is constructed with un extension woll or ring 21 from neer its-outer edge, the double web 22 heine' nrrongod on the inside of this well 21 and arranged between the rings 3, 4:, seid web also carrying eonentrc rings 4 und fi, which mesh with the rings 3, 4, the steam acting on two sets of rings instead of one. l

in action, the lever 11 operating the clutch S ond brake 13 is moved teistert the machine, this action puttin the clutch 8 into `connection with one dis soy 1, and braking the other disk, sty 2, so that it can form s. resistonce to the action of the steam, sind es will he understood from the drawings, the disk 1, clutch 8 and axle 3 moving as one. The steam now enters the casing ot 15, :ind passes to the space 23 around the side 3 und coller 17, and then into the ockets or `recesses 6, zit-,tino1 on the wells cip the pockets of the movzilile disk i, the walls of the hroked disk 2 acting as s resistance, and moving the clutched disk and consequently the axle to drive the machinery,y the steam passing through the pockets and sinuously between the rings until it reaches the churn er 21% sur rounding'the disks and rings, ond sway by the exhaust 16, hy which time the steam hos effected `its maximum, ol power in propelling theelute'hed disk. in Fig. 2,the steam posses into n chsinher 25 between the disks l and 2 std into the chamber 24 h holes 26 in the woll 21. Thus the axle 3 is nriven in one directiqn,-nnd if it is desired to reverse the direction of travel of the axle, the lever 11 is operated to clutch the other disk, say 2, end broke the previous moving disk, say l, when s reverse travel of the axle will take lace', the steam acting as before, due to the isk 1 being broked, and the disk 2 bein clutched to the axle 3 and rendered movob e.

ln some cases, the steam may be admitted to the casing and exhausted near the axle, and 'the sizes of the pockets may be gradually enlarged from the outside rings to the inside. What do claim and desire to secure by Letters Patent istl.. A turbine comprising a casing, a shaft therein, a plurality of revoluble iuid oper ated elements loosely mounted on the shaft and provided with a pair of concentric ren versely tapered brake surfaces, a clutch for alternately eonneeting said elements to the shaft, brakes simultaneously movable axially of the elements and arranged to coperate with said brake surfaces of the respective elements and movable simultaneously axially of said surfaces to hold one element and perinit rotation of the other element, and a member for simultaneously setting the brake on one elenient and engaging the lclutch With another element to operatively connect the latter to the shaft.

2. A turbine comprising a ceasing, a shaft, a pair of revoluble Huid operated elements having a pair of axially tapered brakeu surfaces, a4 pair of operatively connected brakes movable siniultaneouslyin a direction axially of said elements for braking one element and releasing the other, and a clutch connected to operate with said brakes and serving to connect one element with the shaft While the other element is held by its respective brake.

3. A turbine comprising a casing, a shaft, apair of revcluble iiuid o erated elements having o positely tapered brake surfaces, a nair of rakes movable transverse to the essere plane of iotation of said elements for alternately engaging said brake suriaces, and aA brakes for connecting one element tothe shaft and setting the brake on the other element.

5. A turbine comprising a casing, a shaft therein, a pair of iiuid oiierated elements re voluble on the shaft and having coperating rings havinff Huid-passages for conducting the niotive iluid in a direction radially of the shaft, reverse-ly tapered brake surfaces on the peripheries of said elements, a pairl of brakes connected to operate alternately on the brake surfaces of the respective elements.

a clutch for alternately connecting the eleL a lneinber connected ments to the shaft, and to said brakes and the elutoh for connecting one element to the shaft and setting the brake on the other element.

in testimony whereof I have hereunto set iny hand in presence of two subscribing Wit nesses.
